One person has been killed and two others have been wounded in an altercation at the Great Lakes Dragaway in Wisconsin. According to a police spokesman on the scene, they only have a vague description of the shooter, a black male with short hair and cut-off jeans in his 30s. Two were dead at the scene and a third victim was transported to a local hospital where he died. "We don't know if he's still here", Beth said according to reports. "At this point we're not aware of exactly what caused this".

Organizers of the annual event, called Larry's Fun Fest, said about 5,000 people attended Sunday's show. The type of weapon was unknown.

Sheriff David Beth urged any witnesses to the shooting to contact his department. "It didn't take us long to get everybody to leave", Malecki said.

Several thousand people were at the track at the time, which was evacuated.
